To `enable those skilled in `the art to lmake and use `my invention `Iwill proceed to `describe thesame with reference tothe drawings. y i i y Motion may be communicated-through the shaft A, tothe feeding apparatus through a crank, gearing or belts from :any first moving power. On'oneendofthis'shaftA, there is `a bevel pinion a which y: gears with` `and the endof a screw shaft F, that isturned` thereby in its i bearings or` `ilooXes s fb.

to allow the driver I, as well as the nail plate it is carrying forward, to freely pass through it when it is momentarily at rest. To this hub J, and to a similarly revolving disk L, suppo-rted by, and turning in, a ring g, are connected respectively the rear and front ends of the rods la., L, sheath rods z' z', and outer sheath case lc, as follows: The rods h, h, and sheath rods i z', are permanently fastened to the hub J, and of course turn with it, and the outer sheath case la, is permanently attached to the disk L, but made to slide over the sheath rods when the disk L approaches the hub J, which it does every time the plate is to be turned over and fed up. Forward of the disk this outer case or sheath forms the jaws Z Z, in which the plate is controlled or held by spring pressure and through which it is gradually projected at each feed motion to afford suiicient to form the nail. Y

To show more clearly the operation of the entire machine, I have arranged the cutters m, fn., on the same frame with the'nail` plate feeder. In practice such will not be the case, as it may be necessary to adjust the feeder to the cutters, or to change the former when different sized nails are to be made, and the arrangement of the cutters as herein shown, is merely for illustration.

On the shaft C there is a cam wheel M, having a cam groove 0, on one of its faces,'in which a stud p, in the upper end of a connecting or hooked bar N works, said bar having a slot O, in its upper end to allow it to follow the throws or beats of the cam groove 0, and said upper end of said bar N, is held up to the cam wheel by a collar g on the shaft C. The lower end of the rod N, has a hook r, upon it which catches over a wrist s that can be adjusted ina slot t, in the segment wheel K, and when adjusted, it is held there. The segment wheel is hung, or vibrates on a shaft or journals u, so that the motion given to the rod N, by the cam o, is imparted through said rod to the segment wheel K, and by the segment wheel to the hub J, and the nail plate in its case or sheath, each and every movement or rest being timed to suit the action of feedingturning over, or furnishing a fresh nail plate.

There is also a cam wheel P, on the shaft A, having a cam groove fu, in its face, in which a stud w works said stud being fastened to an arm Q, and giving to said arm, an extent of motion equivalent to the throw of said cam groove. This arm Q has a hook in it which catches over a stud or pin y in the bail rod R, and vibrates said bail rod on its pivoted point z. This bail rod is forked at its lower end, so as to form a bail 4 that is connected to ears 5, on the sides of the ring g, said ears taking over rods or ways 6, and by this connection the disk, nail plate holder, &c., are fed to and from the cutters, for the purposes heretofore described.

When the carriage and driver is returning with a fresh nail plate, it is necessary that the hub J, should remain stationary and so that the opening through its center should be in the right position to allow the nail plate and driver to pass through it, as the plate must pass up into the sheath. To effect this result I provide as follows: A lever S, is pivoted at 7, and its forward end is connected to the arm Q, by a rod 8, and to a spring T, by another rod 9. The rear end of this lever lhas a bend l0 in it, which the arm 11 of the carriage Gr strikes, when it is running back preparatory to bringing up a new nail plate-and this arm continuing upon the higher portion of the lever, presses and holds down that end of said lever. There is also an arm 12, on the lever S, which projects downward, and into an opening in a hinged trigger 13. Now the eifect of pressing down the rear end of the lever S, and holding it down is as follows: It raises up the hook clear ofthe pin y, and stops the motion of the disk L; it slips the trigger 13, under the point of the rod N, which raises the hook rin said rod from the wrist pin s in the segment wheel K, thus stopping the motion of said segment wheel and the parts also which it gives motion to, viz: the hub L, &c., and finally it strains up the sprin T, and all these parts continue in this posltion until the carriage returns far enough to clear the lever S, of its arm 11, and the moment this is done t-he recoil of the spring T, brings the hook ab, onto the pin y, and the hook r, onto the pin s, by withdrawing the trigger 13, from under the toe piece of the rod N, and motion is at once communicated to all the moving parts and thus continues until the nail plate is worked up and another one required. The only Vattendance the machine requires is to keep the magazine supplied with plates.

Should the driver at any time stick fast, or the plates get disarranged in the magazine so that either fails to perform its duty, the failure may be made available to throw the machine out of gear, and stop it at once, as the motion continued under such failure must break some part of the machine. To effect this, the magazine H may be placed on ways 14, but held thereon bysprings, so as not under ordinary circumstances to move. But when a nail plate fails to leave the magazine, or the driver fails to properly pass into or through the magazine, the effect will be that the magazine will be forced along on its ways 14, and this motion through a clutch lever 15 will uncouple the shaft C, and consequently stop the feed motion of the driver.

The forward ends of the sheath rods i z' `26,513 e f i a" are bent outward at their forward ends sufliciently to pass through slits in the outer sheath case, so that the end of a nail plate lying in the outer sheath case, can pass freely back within the sheath rods, without meetmagazine into the sheath, these sheath rods may be dispensed with, provided a clamp be arranged in connection with the lever S so as to catch the bail rod R, or the sheath k at thebackward end of their movement and hold them with the back end of the sheath near to the hub J, while the hook a: is disconnected from the pin y; and provided the back end of the sheath be furnished with a spring which will allow the nail plates to pass forward into the sheath but not back` again. j

In order that the frontend or jaws of the sheath may move forward near to the moving knife of the cutter when a nailis to be cut off, and so feed up nearly the whole plate with as little remnant or scrap` as possible, the jaws Z Z may be made thin, relieving them from any strain from the action of the cutter on the nail plate, by what I call a strain bar, which is a bar or strapV attached to the cutter-frame over the lower knife, in front of and near to the upper or moving knife, between which bar and the lower knife the jaws Z Z of the sheath will pass.

The magazine ma be attached to the j sheath and partake o all its movements, the

plates being ressed toward the driver by drawing there may be usedin connection :e i

with the automatic `driver arevolving cyl` inder with its y axis parallel to the driver j or an apron capable ofmotion transversely` y f with respect to the driver, or a table: capable j of the same transverse 1motion, either` of n 1 i "50 will present to the automatic driver afresh i 3 f which by periodical `automatic movements,
